Improvement in envelopes



UNITED STATES OFFICE.

ALEXANDER A. O. KLAUOKE, OF WASHINGTON, DISTRICT OF COLUMBIA, AND JEFFERSON FRASER, OF NEW YORK, N. Y.

IMPROVEMENT IN ENVELOPES.

Specification forming part of Letters Patent No. SEJFQQ, dated April 6, 1869.

To all 'whom it may concern:

Be it known that we, ALEXANDER A. C. KLAUOKE, of Washington, in the District of Columbia, and JEFFERSON FRASER, of New York, in the county of New York and State of New York, have invented a new and useful Improvement in Envelopes; and we do hereby declare the following to be a full and correct description of the same, sufficient to enable others skilled in the art to which our invention appertains to fully understand and use the same, reference being had to the accompanying drawings, which make part of this specification, and in which- Figures 1 and 2 are plane elevations of an envelope provided` with our improvement. Fig. 3 is a view'of the inside of the saine.

Like letters of reference indicate like parts in the several figures.

The nature of our invention consists in providing a common envelope with a punched place, gummed on the inner side or not, as may be desired, in which punched place the address of the sender'of the letter may be printed or written, so that when said punched place is taken out of the envelope by the receiver of the letter, he may paste the same on the envelope of his answer, and thus insure the safe delivery of the same, 'and avoid the labor of superscribing with a pen.

In the drawings, A may represent a common envelope, having a certain space, B, punched or perforated around its border, which may be of any desired shape, so as to enable it to be torn out more easily, and still remain securelyr attached to the rest of the envelope, to prevent its accidental separation. This space may be punched but on three sides, running to the edge of the letter, as shown in Fig. 1, or it ma be punched on all four sides, as shown in ig. 2. This space ought to be preferably above the line of ad-` dress of the envelope, though its posit-ion, It may extend aside from this, is immaterial.

across the length of the envelope at one end of the same, or may be on the Hap on the back, so that tearing it out willopen the letter.

Fig. 3 shows this space B on the inside of the envelope, Where it is gummed, although it is not absolutely necessary to gum it, as the receiver of the letter may do it at his pleasure.

The great advantages of our improvement are, that the envelope is of use to the .receiver as well as the sender, and that the improvement will not add in any material amount to the cost of manufacture of the envelope.

The space B may be punched or otherwise made easily detachable-as, for instance, by indenting it.

The gumming of space B may be done in one operation with the gumming of the flaps of the envelope, and the gum on said space dried by passing that part of the envelope over a heated die or roller whi le the envelope passes from the gumming to the folding apparatus.

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is-

1. An envelope provided'with a space, B, punched or otherwise made detachable, whether gummed on the inside or not, substantially as and for the purpose set forth.

2. An envelope with the address of the sender printed or inscribed on a portion thereof, the boundary of which is perforated, or otherwise prepared so as to be readily detachable, whether made adhesive or not, substantially as and for the. purpose set forth.
